In computing, a protocol is a set of rules which is used by computers to communicate with each other across a network. A protocol is a convention that controls or enables the connection, communication, and data transfer between two computers. In its simplest form, a protocol can be defined as the rules that govern communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of communications between two computers.
